Float issue

Post by Sascha » Thu Mar 31, 2011 11:30 am

Hey guys,

So I took her out for a ride (FOR THE FIRST TIME) yesterday... A few issues I need to work out and wanted to get your input on:

I have no low end idle, the bike is always reving high...
Wondering if its a carb float issue as fuel is coming out of the pipes... Does anyone have a picture of the angle that the little tab on the float should be at? I need a visual to get it right... Tried the other way, didnt work for me.

Other than that she ran strong... Need to tighten the brake lines but she is feeling pretty good.

I did notice a bit of a wobble, wondering if its because of my streering mount? Its a bit squirley?!

Be carefull that you don't overflow your engine and blow out the gaskets.

So while you have this little problem, try to keep eye on the oil-level in the engine.

Don't know how much the little adjust thingy needs to be, I try'd it with trial and error, untill both bowl's where at the same level, of course high enough, so that the main jet always get's fuel.

Think it was about 2mm under the edge from the reservoir, when the bowl's where mounted. ( thus not horizontal )

From what I remember, the round floater bowls in the carb (ya, forget my lacky English, try to understand) , when you push the round floaters up (to shut of fuel) , the round floaters where about 1 or 2mm 'over the edge' in the carb. (so that 1 or 2mm from the floater was 'inside' the carb.)
Then the fuel quitted flowing.

You will see that I mean when you take of the fuel reservoir.

Hope this helps you a little.

And if you engine is always running high, it could also indicate that you have an air leak somewhere.
Head-->Carb mount most likely, but it can also be the head gasket, and it can also be the advancer (maybe worn springs, of loose)
But a simple air leak is probably the cause, or as you say, to low on fuel in the carb's reservoir. (making the mixture lean, as what would happen with an air leak)

Please elaborate Sascha (define squirley). You rebuilt the head parts? How tight/loose did you do the steering head nuts?

Watched your videos! NICE Dream!

Where did you get this bike or did you modify it like this? That bike is going to be getting alot of sell me offers.

First off is the carb still a PW-22 carberator/stock carb? If So, when you have the float bowl off, turn the carb over and raise the floats in the air from the upside down carb so that the top of the floats pointing up in the air now is 26.5 MM above the area for the float bowl seal seat when the adjustment tab is barely kissing the float needle stem. To much fuel drowns engines and they don't run and it dosen't take much. Take a video of your spark plugs and float level. Also I would like to see the idle jet out and held upto a bright light to see the hole that goes though it. Make sure it's not clogged. Also, make sure the idle jet screw and the carb throttle idle adjustment screw arn't switched. =-) IE. look in the carb venturi and see if the screw is sticking out far enough to interfear with the carb throttle slide as it should so it can hold it open for idle. You can turn the screw and see how much it effects the throttle opening. Also the A:F screw has rubber seal on it and the idle adjustment dosen't. At least on my carb. The idle screw is also longer then the air mix screw.
And lastly, Why arn't you using that starter button? :)

Saw your Video on You Tube!

Post by Narly9999 » Sat Apr 02, 2011 4:08 pm

Saw the You TubeVideo.

Saw your post on honda305.com Nice Speedo. Looks like the speedo frooze up. The speedo inside has a megnet that influences the motion of the needle. The alluminum cap that goes over the magnet is what's effected by the magnet. If you look in there it's the body of the TOP looking thing. The top part is only connected to the bottom by the framing and the magnetic field. SO why did your needle have enough force to break if it's not conneted to the speedo cable? Next comment to finish.

@Sascha This top looking thingy is steal on the bottom and alluminum on the top. There is a magnet in the middle attached to the steal side of it(Bottom). It's this magnet that collects iron shavings from where ever it comes from. Maybe the gears? Rusting inside the speedo? But this iron gets between them and fuses them together. Thus causes the needle to wind around and break. There is a little coil spring in there as well. There is a place out in California I would sent it to.

P.S. If someone washed that BEUTIFUL motorcycle with a water and hose, The water flows into the speedo and into that top thingy. If it gets so freeking cold that the water freezes,,, 8-) SNAP! Yeah it would fuse them two parts together cause the water would freeze betwen them. Of course that's why the speedo has to have a good seal to keep water out from rain etc. I've allways told people Motorcycles are not water craft! Don't wash them with water and a hose. Nice soft cloth and some good cleaning agent and some oils maybe. Depends on the surface you are cleaning. Georgious Bike!! I fell in love with it right away. ;-) Let me ride it?
